| 摘 要： | 递归结构建模是目前主流的树木建模方法,具有局部参数的微小变化将引起模拟结果巨大变化的特点,建模过程难于控制。针对递归结构建模方法的上述不足,基于植物自组织结构建模思想,提出树木基本生长单位--芽基于光源竞争的建模方法,从生长环境计算、资源分配以及生长模拟3方面阐述建模过程。实验模拟表明,生成的树木图像逼真、自然,通过控制算法中的参数能有效模拟树木顶端优势、向地性现象和向光性现象等,为树木的建模提供了一种新思路。

| Abstract: | Based on plant’s self-organizing modeling thought, a novel modeling method of trees’ basic growth unit-bud competing for light is proposed. This method consists of three parts: growth environment computing, resource allocation and growth simulation, which is easy to understand and operate. The experimental simulations show that the generated image is lifelike and natural, meanwhile apical dominance, geotropism and phototropism phenomena can be simulated just by several parameters. This paper provides a new idea for trees’ modeling in virtual world. |
